I would suggest listening to any SS preamps that your local dealers have and that price is largely relational to the specific company not across brands.
An example is thus: Say you love the sound of ribbon planar speakers - maybe it is priced at $2k and you like it better than ANY boxed speaker at $10k - you can call it, like some reviewers who feel this way, a giant killer. On the hand if you dislike the sound of such planars, as many many MANY people do, then you will the reverse that a very good $2k boxed speaker rips apart a $15k panel.
This goes for amplifiers, sources, etc. if you are a fan of Single Ended Triode operation with High efficiency loudspeakers then chances are you will find a preamp or integrated for under $5k that you will like better than $150k worth of Krell/Levinson/Soulution/Edge/Celestion etc. We all might agree that that the $50k Krell sounds better than the $3,000 Krell however. So if you LOVE the $3k Krell then you will find the $50k Krell to make sense - it is about raising the bar of the platform of design.
If you buy into the "platform sound" then to you the top model of that platform is justifiable but which may seem crazy to me. Some people are also more picky about certain traits than others - so when I listen to music I may focus more on the tone and timbre and like the ambient energy of an active tube preamp while someone else will listen to that same thing and feel that a passive preamp is more neautral with a more open accurate character. I may view it as lacking definition, body and weight that is on the recording and is being gutted.
So you can audition the exact same thing and have a pretty big difference of what is happening or what you want your music to sound like. So when comparing SS to tube I focus less on the money but the design but then within the same design I find more money almost always equals better to much better sound.
For me the M3 preamp is the exact same design as the M10 preamp the latter is a balls to the walls improvement in parts quality and sound quality. You pays more you gets more - BUT if you don't like the way those preamps reproduce sound then you probably won't understand why the M10 is priced into the stratosphere.
So it sounds like the OP is in the technology sampling stage of seeing which of the preamp technologies suits his preference because in general one will come out on top. The only advice I have is to compare apples to apples - in other words compare say three very well regarded passive premps, three well regarded SS preamps, and 3 SET maker preamps, and 3 PP maker preamps, and heck even OTL or class D. Audition in the same general price ranges as it's not really fair to listen to a $50k SS preamp against a $1500 tube preamp for example.
Lastly, it also somewhat depends on the system one is using as well - the level of resolution the rest of the system has in order to delineate what in fact the premps under test are doing - for instance you could bring in a preamp that throws light on the weaknesses of the rest of the system - it gets the blame for being rubbish when in fact it is the rest of the system that is rubbish and the preamp you think sucks is actually the rock star of the entire system waiting to be surrounded by better gear. That's why I much prefer to go out and hear an AWESOME mind blowing goosebump giving system then writing all the names down of the components and putting that set-up together. Too much buy and sell hit and miss blind buy mixing and matching with guessed at system synergy.
